摘　　要：电动涵道推进器采用永磁同步电机作为驱动电机,对电机的转速响应要求较高。采用矢量控制时需要对电机相电流进行采样,采样过程依赖电流传感器,诸多因素都会造成采样电流波动。改进了传统FOC,舍弃电流环,提出转速环直接控制q轴电压和查表法补偿d轴电压相结合的方法。该方法舍弃了传统的Park和Clarke坐标变换对电流进行解耦,从而减少了算法运算步骤,不需要电流传感器的参与,简化硬件设计,降低成本。仿真和应用实践验证了该算法有效性。The permanent magnet synchronous motor is used as the driving motor for electric bypass thruster,which requires high speed response of the motor.When vector control is adopted,it is necessary to sample the phase current of the motor,the sampling process depends on the current sensor and many factors will cause the sampling current fluctuation.The traditional FOC was improved,the current loop was abandoned,the speed loop direct control of q-axis voltage and the table method for compensating d-axis voltage were proposed.This method abandoned the traditional Park and Clarke coordinate transformation to decoupling the current,thus reducing the algorithm operation steps,and did not require the participation of the current sensor,simplifying the hardware design and reducing the cost.Simulation and application practice verified the effectiveness of the algorithm.
